Brewers, Rangers, Blue Jays and Athletics coach (1970–1984)[edit]

Despite his brief playing stint in the Majors, Moore spent over forty years coaching in the game, most of which has been at the MLB level.

His post-playing career began in the Red Sox farm system in 1968 as the manager of the Jamestown Falcons of the short-season Class A New York-Penn League. In two seasons under Moore, Jamestown went 64–85. He then was hired as bullpen coach for the Seattle Pilots shortly after their one and only season in Major League Baseball (1969), and went with them when they moved to Milwaukee and became the Brewers starting in 1970.[3] He was their bullpen coach through 1972, when he was released at the end of the season.

He was hired by new Texas Rangers manager Whitey Herzog as the Rangers' first base coach shortly afterward for his first stint with the Rangers. After the 1973 season he was retained when Billy Martin took over as the Rangers' pilot in 1974.[4] After one season under Martin, Moore then managed Texas' Double-A farm team, the Pittsfield Rangers of the Eastern League, for the first half of 1975 before returning to the Rangers for his second term as a coach when Frank Lucchesi became their new manager, replacing Martin, in mid-season.

Oakland manager for 21⁄2 seasons[edit]

In 1981, Billy Martin, now manager of the Oakland Athletics, invited Moore to coach first base for his "Billy Ball" team. He remained with the club after Steve Boros replaced Martin in 1983, and eventually replaced Boros as manager on May 24, 1984. In his only full season at the helm, 1985, the A's went 77–85.

The 1986 Athletics' record hovered around .500 until an 8–23 skid dropped the team's record to 29–44 in mid-June, worst in the majors. Moore, who went 163–190 (.462) in his 2+ years managing the A's, was replaced on an interim basis by Jeff Newman, and in early July by Tony La Russa, who stayed in Oakland through 1995 before concluding his brilliant managerial career with the St. Louis Cardinals from 1996 to 2011.

In his five Texas League seasons the Express went 376–324; in the Pacific Coast League, 220–210.

Return to the Majors as a coach (2008)[edit]

On September 30, 2007, he was named the Houston Astros' bench coach for the 2008 season by manager Cecil Cooper. Moore was Cooper's first professional baseball manager with Jamestown in 1968. After just one season, Moore left the Astros to begin his fifth term as a coach with the Texas Rangers, reuniting him with Ryan, now president of the Rangers.[5] During five seasons as the bench coach for manager Ron Washington, the Rangers won two American League pennants, qualified for the playoffs three times, and tied for the second AL wild card in 2013. After the Rangers' defeat at the hands of the Tampa Bay Rays in a one-game playoff on September 30, 2013, Moore, 74, was notified he would not return as the club's bench coach for 2014.[6]
